title: A coherent synchrotron X-ray microradiology investigation of bubble and droplet coalescence.
abstract: A quantitative application of microradiology with coherent X-rays to the real-time study of microbubble and microdroplet coalescence phenomena, with specific emphasis on the size relations in three-body events, is presented. The results illustrate the remarkable effectiveness of coherent X-ray imaging in delineating interfaces in multiphase systems, in accurately measuring their geometric properties and in monitoring their dynamics.
